- Abstract
To increase the supramol. cooperativity in Fe(II) spin crossover materials based on N1-substituted tetrazoles, a series of -(1H-tetrazol-1-yl) carboxylic acids with chain-lengths of C2-C4 were synthesized. Structural characterization confirmed the formation of a strong hydrogen-bond network, responsible for enhanced cooperativity in the materials and thus largely complete spin-state transitions for the ligands with chain lenghts of C2 and C4. To complement the structural and magnetic investigation, elctronic spectroscopy was used to investigate the spin-state transition. An initial attempt to utilize the bifunctional coordination ability of the -(1H-tetrazol-1-yl) carboxylic acids for prepn. of mixed-metallic 3d-4f coordination polymers resulted in a novel one-dimensional gadolinium-oxo chain system with the -(1H-tetrazol-1-yl) carboxylic acid acting as µ2-2:1 chelating-bridging ligand.
